FSB Termination voltage higher than vcore?

[fps_dean]

Is there anything wrong with having FSB Termination voltage higher than Vcore?

I am fairly sure that I need to increase my FSB Termination Voltage.

However my CPU voltage is all happy at 1.28v.

Do I need to increase Vcore or should I be fine?

hi, give me more info please, CPU ,mobo ?

Created a system specs profile.

Motherboard: Asus Rampage Exteme
CPU: Intel Core 2 Duo e8600
RAM: Corsair TWIN3X2048-1800C7DF

Actually trying to get my memory stable. 1.26v FSB Termination voltage passes memtest for 6 hours before freezing, 1.22v or less lasts anywhere from 20 to 60 minutes before freezing and I'm fairly confident that 1.30v will go forever....

my Q6600 @ 3ghz needs 1.25 FSB term 1.2 on vcore so FSB term I think is higher than vcore

No problems?

I think I have mine set to 1.4v

Is there anything wrong with having FSB Termination voltage higher than Vcore? no wrong 1.30 V it's good.

Thanks a ton guys.

I've always read that it shouldn't be higher so I just wanted to be sure.

Very high VTT voltage (FSB Termination voltage) can have an unhealthy effect on 45nm CPU's, especially quads, as per Ananadtech report:

Beware of VTT - it's a lurking time bomb...

It killed their QX9650 sample in a few months. As per their posting, and I quote: "Let this be a warning – do not go over 1.4V maximum for 24/7 use!"

Apparently 65nm CPU's can handle high VTT voltage just fine (also known as FSB Termination voltage), 45nm ones are not so resilient.

I am aware of this. 45nm CPUs run 0.1v lower than 65nm CPUs, but there's a lot more evidence to suggest that high Vcores (above 1.4) kill CPUs faster.

Don't worry - not going for anything too crazy here, just trying to get memory stable at 1800mhz.

But thanks for the heads up.
